Vitamin D benefits have recently been touted in the popular press. However, it seems there is an epidemic vitamin D deficiency in the population. This is especially true for the elderly with estimates of 40 to 60% of this population being “D-ficient”. In the younger segment of the population it is postulated that up to 32% have critically low levels. These alarmingly high rates of deficiency are not surprising considering that Vitamin D synthesis in the body requires exposure to the ultraviolet (UV) light of the sun’s rays, few foods in our diet contain adequate levels of this important vitamin, aging skin is not as efficient in absorbing UV light required for its synthesis and obesity impairs its actions in the body. Deficiency in vitamin D is linked to a whole host of health problems: cancer, multiple sclerosis, diabetes, osteoporosis, heart disease, muscle weakness to name a few.
